While MSI wasn't quite ready to publicly divulge all the details of its forthcoming X79-based motherboards, it was more than happy to give us a teaser. We were shown three upcoming models from the company at IDF, all toting PCI Express 3.0 slots, overclocking buttons and that snazzy UEFI BIOS. The latter makes changing settings a snap, and is carried over from the company's existing Sandy Bridge boards -- it even comes with a button that launches a browser, but unfortunately the machines in the booth weren't configured to support it. We'll know more in Q4, but in the meantime a gallery awaits you below, along with a video after the break.
